Long-term impact of atrial fibrillation catheter ablation on heart failure with preserved ejection fraction.

Background: The efficacy of catheter ablation as a treatment approach for patients with concurrent atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) has been inadequately investigated.

Objective: This study's objective was to assess the effectiveness of atrial fibrillation ablation (AFA) in patients with heart failure with preserved ejection fraction.

Methods: Utilizing the TriNetX research network, we identified individuals aged 18 and older with atrial fibrillation (AF) and concurrent heart failure with preserved ejection fraction (HFpEF) from January 1, 2010, to June 1, 2021.

Non-traditional factors affecting referral for coronary angiography following SPECT myocardial perfusion imaging.

Background: The use of myocardial perfusion imaging (MPI) in the management of coronary artery disease (CAD) is well established. Although prior studies have shown disparities in the use of invasive angiography in patients with acute MI, data on factors affecting referral to angiography post-MPI are lacking. We sought to evaluate the primary determinants of referral to invasive angiography post-MPI and specifically assess the role of non-traditional non-clinical factors such as race/ethnicity, socioeconomic factors, insurance status, and marital status.

Catheter Ablation for Atrial Fibrillation in Patients With Concurrent Heart Failure.

Due to limited real-world data, the aim of this study was to explore the impact of catheter ablation (CA) for atrial fibrillation (AF) in heart failure (HF). This retrospective cohort study identified 119,694 patients with AF and HF from the Nationwide Readmissions Database (NRD) from 2016 to 2017. Propensity-matching was generated using demographics, comorbidities, hospital and other characteristics through multivariate logistic regression.
